If no color change is observed when solution B is added, then the substance contains MDA, amphetamine, or MDPV. So every drug that Simon's reacts with will theoretically have a secondary amine group. The Chen-Kao test is performed by creating an acidic solution of the compound to be tested and adding dilute Copper (II) Sulfate and Sodium hydroxide solutions.The procedure is as follows: Further, the coordination complex might be extracted with organic solvent like diethyl Ether or n-butanol (see Table II), as proposed in the literature,[8][9] which provides additional confirmation of the original results, but no further differentiation. Simmons Citrate Agar is an agar medium used for the differentiation of Enterobacteriaceae based on the utilization of citrate as the sole source of carbon. This precipitate could be seen as characteristic for the members of the ephedrine group other than pseudoephedrine and ephedrine itself, hence, the Chen-Kao test appears to show a significant specificity within the ephedrine group. 37 (1958) 323. 0000047358 00000 n

In the early 1920s, Koser developed a liquid medium formulation for the differentiation of fecal coliforms from the coliform group. These faster rates are associated with lower activation energies. Never open more than 1 bottle at once, if you make a mistake you might contaminate the reagents and spoil them. Replace the cap. Much like Marquis, Mecke changes to a dark purplish color when testing pure MDMA. My Account Shipping FAQs Menu My Account Shipping FAQs Home Testing Kits United Nations, New York, NY. (see Table III)[4], When acidic solution of ephedrine or pseudoephedrine is mixed with copper sulfate and sodium hydroxide solutions, a violet color is formed. Merck Microbiology Manual 12thEdition-SIMMONS Citrate Agar. xref
The amine and acetaldehyde produce the enamine, which subsequently reacts with sodium nitroprusside to the imine. 1. In order to further differentiate between ephedrine enantiomers - ephedrine, pseudoephedrine and other ephedrine-related compounds, Simons test (with acetaldehyde) and Simons test (with acetone) are used. Dipotassium Phosphate actsas a buffer. It is one of three reagents in the MDMA kit.

Mandelin is particularly useful for testing molly samples, because its able to detect a potential deadly adulterant that is now rarely(thankfully) sold as MDMA. Unfortunately, sometimes two different drugs may have a nearly identical reaction with a given reagent, such as MDMA and MDA with marquis reagent( both turn purple-black). 13 (1975) 327.
